Question
Give reason for the following:
The size of a Cl− ion is greater than the size of a Cl atom.

Solution
An anion gets formed when one or more electrons are gained. Thus, there are more electrons than protons. The nucleus's effective positive charge is reduced, resulting in less inward pull. As a result, the size becomes larger.
